Highlights
- Arkham Intelligence launched live wallet tracking for Pump.fun and Fomo trader profiles, letting users search any username to surface the wallet behind it.
- The feature shows every trade a tracked wallet makes plus its wider on-chain activity, extending Arkham's existing wallet-tracking tools.
- Arkham highlighted one Fomo trader who turned a $117,000 position built over 65 buys into a $3.2 million unrealized gain, a roughly 28x return.
- The trader built the position over five weeks starting at a $2.7 million market cap for the token STONK, which has since grown to a $268 million market cap.
- The launch deepens the wallet-tracking arms race already underway between Pump.fun, which acquired the Kolscan tool in 2025, and rival platform Fomo.
Search a Username, See the Wallet
Arkham Intelligence has switched on live wallet tracking for trader profiles on Pump.fun and Fomo, the two leading Solana meme-coin trading platforms. The feature lets any user search a trader's username on either app and instantly surface the wallet address behind it, then follow every trade that wallet makes alongside its wider on-chain activity. The move extends tools Arkham has built over the past year for tracking influential crypto accounts and gives retail traders the same kind of surveillance capability that professional on-chain analysts have used to spot early buyers before a token's price takes off.
A 28x Trade as Proof of Concept
Arkham illustrated the feature with a concrete example: one of the largest accounts on Fomo spent $117,000 building a position in a token called STONK across 65 separate buys beginning five weeks earlier, when the token's market capitalization stood at just $2.7 million. STONK has since grown to a $268 million market cap, and the trader's position shows an unrealized gain of roughly $3.2 million, a return of about 28 times the original outlay.
The launch builds on capability Arkham introduced earlier this year, when it rolled out wallet tracking for X accounts with more than 100,000 followers and expanded its Intel API to let users detect clusters of wallets buying the same token in coordination, follow treasury deposits into exchanges, and build custom dashboards or bot alerts. Extending that infrastructure to Pump.fun and Fomo specifically puts Arkham in more direct competition with the wallet-tracking tools native to each platform: Pump.fun itself acquired the analytics tool Kolscan in 2025 to offer similar trader-level insights, while Fomo, founded by former dYdX engineers, has built its own leaderboard and copy-trading features around wallet visibility since launching last year.

Lowering the Barrier to On-Chain Sleuthing
The feature matters because meme-coin trading on Solana has increasingly become a game of information asymmetry: the traders who spot a new wallet accumulating a token early, before a chart moves, capture returns like the 28x seen on STONK, while later entrants chase a price that has already run. By making that kind of tracking available to any user searching a public username, Arkham is lowering the barrier between professional on-chain sleuths and retail traders who previously relied on secondhand tips or paid alpha groups to identify wallets worth following.
It also raises the competitive stakes between Pump.fun and Fomo, which have spent the past year building overlapping feature sets to retain traders as volume rotates between the two platforms. A neutral, third-party tool that works across both apps reduces the switching cost for users who want wallet-tracking regardless of which platform they trade on, potentially commoditizing a feature each platform had positioned as a point of differentiation. For Arkham, the expansion also reinforces its broader thesis that on-chain intelligence, not just price charts, is becoming core trading infrastructure across both centralized influencer tracking and the more chaotic, fast-moving world of Solana meme coins.
What to Watch Next
The real test for Arkham's new feature will be whether it can keep pace with the speed at which Pump.fun and Fomo wallets rotate; meme-coin trading cycles often run in days or hours rather than weeks, and a tracking tool is only as useful as its ability to surface a promising wallet before, not after, a token has already made its move. Traders will also watch whether Arkham extends the feature beyond Solana to other chains where meme-coin activity has picked up, and whether Pump.fun or Fomo respond by tightening the wallet-level data they expose natively. For now, the $3.2 million STONK example gives Arkham a clear proof point to market the tool around as it looks to convert casual searchers into regular users.
FAQ
What does Arkham's new Pump.fun and Fomo feature do?
It lets users search any Pump.fun or Fomo trader username to find the wallet behind it, then view every trade that wallet makes and its broader on-chain activity.
What example did Arkham use to showcase the feature?
A Fomo trader who spent $117,000 across 65 buys on the token STONK, starting at a $2.7 million market cap, and is now sitting on a roughly $3.2 million unrealized gain as the token's market cap reached $268 million.
How does this compare to Pump.fun and Fomo's own tools?
Pump.fun acquired the wallet-tracking tool Kolscan in 2025 and Fomo built its own leaderboard and copy-trading features; Arkham's launch offers a similar capability that works across both platforms from one place.
Is the wallet-tracking feature limited to Solana?
The initial launch covers Pump.fun and Fomo, both built on Solana, though Arkham has a history of extending tracking tools to additional chains over time.
